Germany, assignor to Daimler-Benz Aktiengesellschaft, Stuttgart- Unterturkheim, Germany Application April In Germ s, 1935, serial No. 14,503 any April '3, 193i 1 Claim. (Cl. 1380-112) l This invention relates to springing, systems for power driven vehicles having independently guided vehicle wheels and has for its object to improve such springing systems in which the sus- 5 pension means for the individual vehicle wheels, for example swinging half axles, links or `leaf springs, `are carried singly or in pairs on a shaft member which ismounted on a corresponding member on the frame with the interposition of rubber cushioning means.

l In order that the rubber cushioning means may produce the action required of them they have to be inserted between the relatively movable axle members with considerable initial stress which g renders the assembling on and the removal lof the suspension system from the'vehicle a very 'dilcult matter. 'I'he present invention has for its main object to provide a springing system of the type described which will be capable of easy removal from the vehicle. With this object in view, the present invention consistsin providing the rubber cushioning means in the form of a bush with a reinforcing sleeve which is housed in the tubular frame and bolted'thereto or se'- cured thereto by means passed through the tubular frame, and through the shaft on which the suspension means for the wheels are mounted, the said shaft being preferably either connected to the transverse pin 30 through the intermediary of an elastic body or the transverse pin being elastically mounted on the frame. v

The invention is illustrated by way of example in the accompanying drawing in two embodiments.

Fig. 1 shows a wheel suspension structure having two parallel laminated leaf springs, in crosssection on the line I-I of Fig. 2 and Fig. 2 shows the arrangement according to 4o Fig. 1 in longitudinal section;

Fig. 3 shows a modified detail arrangement of the structure shown in Fig. 2.

Referring to Figs. 1 and `2, q is one Y wheels, for instance the front wheels of a power driven vehicle, which are sprung and supported by means of transverse leaf springs r1, rz secured of a transverse pin` ofapairof to a common central member c having a reax-,

wardly extending tubular shaft s1. The shaft s1 isinserted inatubular rubberbodyt: whichis in the open end of .aber s and, together central memberc and from turning relatively to surrounded by a rigid sleeve t4 which is inserted a central tubular frame memwith the rubber body ta. the the wheel supporting means thereon forms an axle unit. The sleeve t4 is provided with a flange f which is bolted to a terminal flange d on the tubular frame .athereby retaining the entire axle unit in position on the frame. v

In order to prevent the rubber body or bush t: the shaft s1 and the sleeve t4 it may be secured by vulcanization of its inner surface to the shaft s1 and of its outer surface to the sleeve t4. By this means limited rotary motion of the central support c about the longitudinal axis of the shaft t4, and incidentally of the vehicle is possible, the rubberV bush ta being stressed in torsion.

Insteadof the rubber bush t: being vulcanized to the shaft s1 andthe sleeve t4. it may be held under pressure between the shaft and the sleeve. f In the modied constructional form shown in Fig. 3 the shaft s; of the central member c which carries the leaf springs n and rz is provided at its rear end with an eye u: which is lined .with a rubber bush u: through which is passed a pin ul,

- which extends through the frame tube s1. By this means the central supporting member c is sel cured to the frame tube in such a manner that it lis capable of yielding elastically to a limited extent in all directions.

What I claim isz- A springin System combination a hollow for vehicles, comprising in frame 'member, a rigid sleeve inserted in the frame member, a rubber.

bush in said rigid sleeve, a shaft member in said rubber bush having a central support thereon, wheel guiding means for a mounted on said support, said rubber bush being applied to the shaft and (rigid sleeve, so as to permit of a limited amount of rotary motion of the shaft and the frame member relatively to one another, au eye on the shaft behind the rigid sleeve, a rubber bush in said eye, and a pin removably arranged through said bush and transversely' through the hollow frame member, substantially as and for the purposes set forth.
